An osmosis investigation was conducted using 20 chicken eggs to represent cells with semipermeable membranes. The eggs were first soaked in vinegar to dissolve the shell. The eggs were then transferred to corn syrup for 24 hours and then to distilled water for 24 hours.

The table below shows the average mass of the eggs at each step of the investigation. Based on this experiment, which of the following should be inferred about cells with semipermeable membranes? A. Substances other than water may also cross the cell membrane. B. Substances other than water may block pores in the cell membrane. C. Water enters the cell when placed in environments of high water concentration. D. Water leaves the cell when placed in environments with a low concentration of solutes
